I'm narrowing down my options for an AR-10, and I'm liking the RRA LAR-8 more and more because it takes FAL magazines.
My question is, if I have this rifle, is it feasible (and hopefully easy) to build additional uppers in other calibers that are derived from the .308, and will they ALSO work with FAL mags? (7mm 08, .243, 260, .22 CHeetah?) Do I just build another upper with a barrel chambered for the other cartridge and shoot it? If there are gas system adjustments I can handle that.
